What is TrustMark Approved Trader?

A TrustMark-approved trader is a business registered under the UK government-endorsed TrustMark scheme, which vets tradespeople working in and around the home for technical competence, customer service standards, trading practices and appropriate insurance. Registration is delivered through approved Scheme Providers such as FENSA, Gas Safe and the NHBC. TrustMark registration is a mandatory requirement for accessing certain government-funded home improvement schemes, including ECO4, the Great British Insulation Scheme and the Boiler Upgrade Scheme. Consumers can search for approved businesses at trustmark.org.uk and submit complaints through the TrustMark dispute process.
